So good I bought another one...

I purchased this same battery from MC Superstore a couple years ago for my HD Sportster and it has performed perfectly. So the battery on my wife's Sportster needed replacing and why not stay with a proven winner? Yuasa is one of the best. MC Superstore had a very good price, shipping was pretty good- battery arrived undamaged.

Works on 4th Gen also

While not specified, also fits 2014-2015 models without any changes. Fitment was perfect and sounds awesome without being too loud. Saves quite a bit of weight over the stock mufflers as well. No power commander needed- little bit of decal popping at first but this went away after a couple rides and the bike adjusted for it.

DON'T buy Bikemaster TruGel Battery

I purchased 2 of these batteries March 2014 (BMW R1200GS, Suzuki DL650). The BMW had a hard time starting when it was new, now that it is 1 year old it will not start. Suzuki was good at first, but now it will not even hold a charge to light the dash lights. Both bikes are stored inside and are always on a battery tender. Never had this problem with old school lead-acid batteries. Junk... just say NO!
